Explanation:
Detailed explanation-1: -Three major types of filaments make up the cytoskeleton: actin filaments, microtubules, and intermediate filaments.
Detailed explanation-2: -In eukaryotes, there are three types of protein fibers in the cytoskeleton: microfilaments, intermediate filaments, and microtubules.
Detailed explanation-3: -The cytoskeleton has three different types of protein elements. From narrowest to widest, they are the microfilaments (actin filaments), intermediate filaments, and microtubules. Microfilaments are often associated with myosin. They provide rigidity and shape to the cell and facilitate cellular movements.
